A welfare call at a Murphy residence turned into a three-hour standoff Saturday and ended in an arrest.

Police responded to the call in the 200 block of Grantham Lane after Bradley Barrows' girlfriend told police he was threatening to harm himself. Two officers went into the home and asked Barrows to show himself. They exchanged words and Barrows, 18, fired a rifle in the direction of officers who were halfway up a staircase to go talk to him, said city spokesman Celso Martinez in a statement.

The officers weren't injured, but they exited the home and called for back up. Around 12 a.m., police arrested Barrows and transported him to Green Oaks Psychiatric Hospital for assessment.

Barrows will be charged with two counts of aggravated assault with a deadly weapon on a public servant.

Each charge carries an automatic $100,000 bond.

Murphy City Manager James Fisher acknowledged in a statement that it's been an "unusual" year for Murphy. In May, Amy Picchiotti and Jonathan Masin were found shot to death in a Murphy home. Police found the body of the suspect, Michelle Boyer, and a suicide note in a car northeast of White Rock Lake. Officials believe a love triangle led to the deaths.

Fisher said the incidents show residents the result of "training, disciple and prudence" in the police department, "a comforting revelation to victims, innocent bystanders and the public in general."
